Buying Guide

FAQ
- What diameter should I look for in a gasket?
Most standard wide-mouth jars use roughly 3.75″ outer diameter rings with about a 2.75″ inner opening. - Are these gaskets safe for canning and freezing?
Yes, silicone gaskets labeled as food-grade and heat-safe are suitable for canning and refrigeration; avoid exposing non-food-grade materials to food. - Can I use the same gasket on different jar brands?
